This invention relates to improvements in machines for use in shoe making, and is illustrated herein as embodied in a machine for separating lasts and shoes. The invention may be utilized, also, in some of its aspects,

in machines for mounting shoes on lasts. In various of its aspects, however, the invention is not limited to either of these uses.

In the manufacture of boots and shoes the m last, over which the shoe has been shaped,

must eventually be removed from the shoe.

In removing or pulling the lasts, it is dif-' ficult to avoid such a strain on the shoes as to break out" or more or less seriously damage some of them.

size of the shoe.

One object of this invention is to provide improved means for separating lasts andshoes whereby any objectionable strain on the shoes will be reduced to a minimum.

In one aspect, the invention comprises a ranged to slip before placing such a strain on a tightly-lasted shoe as to break it out.

In this aspect, an important featureof the invention resides in a novel actuating mecha nism for bringing theco-operating'm-embers into engagement with a shoe and removing it from its last. Springs are utilized in order that the engagement may be yielding, and an adjustable abutment positions the bottom-engaging member according to the is so arranged that it'may be under the constant control of the operator when the styles of shoes to be removed change often, while on the other hand it may be quickly adjusted for automatic actuation when there is a considerable run of shoes of the same style, with the operations varied to suit the Moreover, the mechanism particular style. This flexible control allows variation and adjustment to arrange for the minimum strain which is sufficient to remove a shoe of any given style, and is made possible by an improved stopping and starting mechanism which, while of'possible general applicability, is especially adapted to machines of this type. Moreover, Whether the machine is operating automatically or under manual control, movement ofthe shoe engaging members may be stopped instantly in an emergency. In the illustrated construction, this is done by complete depression of the treadle which controls the stopping and starting mechanism.

In other aspects the invention provides a fabric or belt interposed between the roll and the shoes for keeping the. shoes clean when shoes of dilferent colors are being pulled.

The hereindisclosed novel method of moving tion, and moving the fabric while thus I pressed against the shoe frictionally to move the shoe relatively to the last, is not claimed herein but is disclosed and claimed in United States Letters Patent No. 1,678,165, granted lJuly 24, 1928, upon my copending application, Serial No. 518,294. Moreover, certain 0 novel combinations disclosed but not claimed herein are disclosed and claimedin United States Letters Patent No. 1,678,164, granted July 24, 1928, upon my copending application, Serial No. 443,043.

.Various other novel combinations and specific constructions will be obvious from the following-description of the accompanying drawings of an illustrative machine, in which Figs. 1to 4 are diagrammatic views showing the operationof the machine Fig." 5 is a side elevation of the machine with the casing broken'awayto show the enclosed mechanism; i

Fig. 10 is a section on the line 1010, Fig. 7; and

Fig. 11 is a diagram showing the use of a fabric or belt to avoid soiling the shoes.

The machine comprises a last-pin 300, which supports a last L while a roll 100 is brought into engagement with the counter and another roll 200 with the bottom of a shoe S on the last as shown in Fig. 2. The last block B having first been removed, the

-- roll 100 is rotated by suitable gearing until the counter portion of the shoe clears the heel portion of the last,as shown in Fig. 3, whereupon the shoe is moved longitudinally off the last by rotation of the roll 200 in engagement with the shoe bottom.

The actuating mechanism of the machine is inclosed in a casing having a removable cover 22 and providing bearings for shafts 24, 26 and 28. Power is supplied from a motor 30 through a belt 32 to a worm 34 which meshes with a constantly rotating worm gear 36 that is loose on the shaft 24. Secured to I the worm gear 36 is a toothed gear 38 engaging a constantly-rotating gear 40 which is loose on the shaft 26 and which in turn rotates a gear 42 that is loose on the shaft 28.

The worm gear 36 is arranged'to be se- I cured to the shaft 24 by a Horton clutch (Fig. 9) actuated by elevation of a push-rod 52 against a spring 54, through oscillation of a bell-crank56 bearing a pawl 58. The bell-crank 56 is oscillated by horizontal motion of a treadle 60 against a spring 62. Actuation of the clutch 50 in this way by the treadle 60 causes one revolution of shaft 24,

' after which the clutch is disconnected as is ered position as shown in Fig. 1 until the. next operation of the machine.

pull the roll 200 downwardly away from a shoe which has just been removedfrom its last, from the position shown in Fig. 4 to that shown in Fig. 1. This action comes just as the shaft 24 stops at the end of its cycle, and the roll 200 remains in its low- When permitted by rotation of the cam 210 out of engagement with the cam roll 208 at the very beginning of the. cycle of the shaft 24, the roll 200 is raised into yielding engagement with the shoe by the action of a sprlng 212 on the outer end of the lever 202.

The tension of the spring 212 may be varied by an adjusting nut 214.

The position of the roll 200 longitudinally of the shoe is determined by a lever 216 that is loose on the shaft 26 and is connected to the frame 206 by a link 218. The opposite end of the lever 216 is held by a spring 220 against an abutment 222 the position of which may be adjusted by a hand wheel and worm 224.

At the proper time in the cycle of opera tions, the roll 200 is rotated in engagement with the shoebottom by sprockets 226 and chain 228 driven by the shaft 204 which is rotated by means of a gear 230 meshing with a gear 232 that is fast on the shaft 26. The shaft 26 is rotated from the gear 40, through a clutch indicated generally at 234 (Fig. 9), arranged to be actuated against a spring 236 by a wedge member 238 operated by a rod 240.

The roll is, in starting position, held out of engagement with the shoe by a cam 110 which rocks a bell-crank 102 carrying a cam roll 108. As shown in Fig. 5, the roll oo 100 is mounted in the upper end of a frame 106, which, at its lower end, is fulcrumed upon the shaft 28 to permit swinging movement of the roll 100 toward and from the counter portion of the shoe S. The belt to crank 102 also is fulcrumed upon the shaft 28. Pivotally mounted upon an arm of the bell crank 102 a link 103. A sleeve 105 is rigidly connected to the frame 106, and the link 103 is freely slidable within the sleevgg 1 105. A compression spring 112 surrounding the link 103 normally holds the-sleeve .105

down against a stop shoulder 107 formed upon the link 103. lVhen the shaft 24 is rotated in a counterclockwise direction, as: 195 viewed in Fig. 5, the rotation of the cam 110 causes the bell crank 102 to be rocked in a counterclockwise direction, and the bell crank 102, through the spring 112, rocks the frame 106 in a counterclockwise directioing 110 carrying the roll 100 yieldingly into engagement with the counter portion of the shoe and causing it to exert a'localized pressure against the rear end of the shoe. At the conclusion of the cycle of operations the canL'3 110 r turns the roll 100 to the position illustrated in Fig. 1, against the opposition of the spring 112. A nut 113 is provided for adjusting the pressure of the spring 112.

The roll 100 is rotated for the propeit e period during the cycle. ofthe machine by sprockets 126 and a chain 128 driven by the shaft 28 which is operatively connected to the gear 42 by a clutch actuated by a puslr rod 140 and a wedge member 138 (Fig. 7)?.-.

When it is necessary to change frequently from shoes of one color to those of another, the lighter colored shoes may be soiled by coloring matter left on the rolls 100 and 200 by the darker-colored shoes. In such case; 1153 7 does I a rubber surface.

there may be provided fabrics or belts F passing around either or both of the rolls, as shown diagrammatically in Fig. 11. Such belts are also useful to prevent skidding or with the shoeS, and to move the rolls back to initial position at the end of the'cycle. When the machine is to be operated automatically, as in handling a run of shoes of approxinmtely the same style, the clutch actuating rods 140 and 240, which govern the rotation of the rolls 100 and 200, are operated by a cam 64 on the shaft 24. The cam 64 is engaged by a cam-roll 66 on a three-arm lever 68 pivoted on the frame at 70. One arm of the lever 68 is connected to a sleeve 142, and another to a link 72 operating a lever 74 com'iectcd to a sleeve 242.

The sleeves 142 and 242 are connected to clutch-actuating rods 140 and 210 (Figs. 7 and by spring-pressed, detents 144, 244

which engage said sleeves and are carried by er sleeves 146, 246, the latter-en aging adjustable abutments 148, 248. Each or these abutment-s 148, 248 is threaded on a second inner sleeve 250, splined on rods 140, 240, as

shown in detail in big. 10 for rod 240. Springs 152-, 252 are maintanied on rods 140,

240 between inner sleeves 250 and adjusting to facilitate relatching of the detents.

The further either abutment 14801? 248 is' adjusted away from the corresponding sleeve 146 or 246,the greater the throw of the cam 64 required to close the corresponding clutch, and consequently the later inthe cycle of o eratio-ns will roll 100 or roll 200 begin to rotate. The closer the stop 156 or 256 is adjusted to the detent 144 or 244, the less the throw of the cam 64 required to trip the de tent, and consequently the earlier in the cycle of operations will rotation of roll 100 or 200 be stopped. The usual adjustment of these parts is such that the roll 100 begins to rotate immediately after engaging the shoe, as shown in' Fig. 2, pulling the counter portion of the shoe off the last. The abutment 248 is adjusted to start rotation of the roll 200 when-the counter has cleared the last, and the stop 156 is set to stop therotation of the roll 100 immediately thereafter. Thestop 256 may be set to stop rotation of the roll 75 200, if desired, when the shoe is in the positionshown in Fig. 4, or it may be set just too high to be reached by the cam 64, for emergency use as hereinafter described, and the end of the cyclerelied upon to stop the roll :89 200. In any case, at the end of the cycle, the sleeves 142 and 242 are moved, by the rotation of the cam 64, into positions whereat they are re-engaged by the detents 144 and 244 respectively, in readiness for the next cycle. The exact length of time that the roll 100 should be rotated before rotation of the roll 200' should commence depends on the style of the shoe. When any one style is operated on for only a short period, it is undesirable a; 99 be obliged to. adjust the abutments 148, 248 and the stops 156, 256 so often, and manual control is preferable. Accordingly, the cam roll 661s made readily removable, to throw the cam 64 out of operation, and the clutch actuating rods 140, 240 are arranged for controlby: vertical oscillation'of the treadle 60.

l he-lever T4 is fixed on a rock-shaft 76, connected by an arm 78 to a link 80, adjustable at 82, and pivoted at 84 onan arm 86 pulled up' wardly by spring '88 and arranged to i be pushed downwardly by the treadle 60 oscillating a rock-shatt- 90. l Vhen using this manual control, and after removing the camroll 66, the abutments 148, 248 and the stops- 156,256 are so set that a small downward oscillation of the treadle 6O acts through the link 80, the lever 74, the link 7 2, and the lever 68, to actuate the rod to cause rotation of the roll 100. Slightly greatermovement of 1119 the treadle 6O acts through the link 80 and the lever 74 to start the rotation of the roll 200, and if desired the stop 156 maybe set to stop the roll 100 at the'same time. If pre; ferred, the stop 156 may be set to trip the de tent 144 and stop the rotation of the roll 100 after the treadle 60 has been pushed a little further down. In either case, the stop 256 is set to trip the detent 244 and stoprotation of the roll 200 when thetreadle 60 has been pressed down as 'far as it will go.

It isto be noted that, whether the machine is being operated automatically or under manual control, complete depression of the LZLJ treadle 60 stops rotation ofboth rolls 100 and 200, and is available to prevent damage to the shoe in ademergency. Moreover, as a further'emergency measure, either detent 144 or 244 may be tripped by hand. This makes it 139 possible to operate either roll 100 or 200 separately if desired. 7

The last pin 300 is carried by a block 302 (Fig. 6) slidable in an arm304: rising from the casing and adjustable by turning a threaded connection 306. It is pressed by a spring 308 into a position for convenient positioning or removal of the last L. A detent 310, operated by a finger piece 312, holds the last pin in operative posit-ion against the tension of the spring 808. The arm 304, the pin 300 and the parts connecting the pin 300 and the arm 30% thus constitute a last support.

In operation, it the machine is being operated automatically, the last L carrying the shoe S is placed on the last pin 300 and oscillated downwardly into the position shown in Fig. 1, and the treadle 60 is kicked sideways.

Thereupon the rolls 100 and 200 are moved bodily into enga ement with the shoe (Fig. 2), the last block B is removed while the shoe is compressed against the last, the roll 100 is rotated to pull the counter portion of the shoe oil the heel of the last (Fig. 3), and the roll 200 is rotated to push the shoe longitudinally ofi? the last. It is convenient to leave the shoe supported loosely by the last (Fig. 4). The rolls 100v and 200 return to starting position and the actuating mechanism comes to rest. The operator trips the detent 310, whereupon the spring 308 presents the last and the shoe in a convenient position for removal. If anything goes wrong during this cycle, the treadle 60 may be completely depressed, to cause the cam roll 66 idly to leave the cam 64 thereby to stop rotation of both rolls 100 and 200.

If the machine is being operated under manual control, the cam-roll 66 having been removed, the procedure is the same except that the operator keeps his foot on the treadle 60 and governs the stopping and starting of the rolls 100 and 200 by depressing the treadle by degrees. The period of rotation of shaft 24; is such that the most tightly lasted shoe can be removed from its last in this way before the cams 110 and 210 return the rolls 100 and 200 to initial position. Emergency use of the treadle 60 is the same as described above.
